Abstract
The LHCb Experiment is commissioning its first upgrade to cope with increased luminosity of LHC Run3, being able to improve on many world-best physics measurements. A new scintillating fiber-based tracker (SciFi) replaced the outer and inner trackers, providing improved spatial resolution and granularity for the new LHCb trigger-less era, with a readout capable of reading zero suppressed data from ~524k channels at 40 MHz. The fully automated calibration of SciFi Front-End Electronics is based on dedicated software tools and operational procedures, validated during SciFi commissioning. This paper describes the design, implementation, and calibration of SciFi electronics and presents results showing the detector performance after commissioning.
